Body for the MP Rotate

Hi for all,
Can anybody please tell me which body should be better foe MR Rotator: 1804 (RainBird) or PROS-04 (Hunter).
I plan to use about 40 MP Rotators in 3 zones (see: http://sprinklertalk.com/wbb/index.php?page=Thread&threadID=2940)

Can some-one who has used the MP ROTATORS in cold climates give me an honest oppinion on thier reliability? ?(
I had about 10 of the mp3000's installed last fall and they were blownout for the winter and are working fine this year. Not sure about longterm but they definitly handled this winter and it was quite a winter up here (I live in Toronto)

I'm not familier with the MPR40-04-CV spray body. I used the Rainbird 1800 series bodies.

With the 1800s, the MP Rotator sits ALMOST flush with the top of the body. The collar of the MP Rotator that you turn to adjust the arc sits on top of the spray body. So there is somewhere between 1/8" and 1/4" of the MP Rotator sitting above the surface of the spray body.

Read my above post. I pressure tested the MP and didn't have a problem here, I am assuming you will be just fine during blow out winterizations.

One thing to remember about Walla Walla and the MP Rotator. The parent company of Walla Walla is Nelson Irrigation. Not the Nelson that us turf guys know, but a company that has focused on agricultural irrigation for years and years. They formed the Walla Walla brand to avoid confusion with the Nelson we all know. The agricultural irrigation folks in general are very, very focused on product quality as their products are used for cash crops. They think these things through a lot more than the turf industry. If you compare the MP Rotator with Rainbirds product, you can see how much different the engineering slant is. The MP was designed and built to be a high quality product. The RB one was designed and built to be a competitive product. There is a big difference in building to be the best and building to be a competitor.

Ray - As much as I agree that RB's attempt at this product is mediocre at best, I think you really need to take a good look at RB and understand who they are. To characterize them as "evolving" into irrigation is very incorrect. Take a walk around almost every irrigated park or golf course in North America....

You might be incorrectly painting Rainbird in newbie colors, since, as the originators of the impact head, they've been major players for several generations. The various manufacturers do have a history of rushing product to market, with clearly mixed results. Wintertime seems to fall outside of a lot of design considerations.

The MP rotator has been in development by the company that manufactures them (Wolla Wolla) for about 2 years...the product has been carefully designed and developed. The end of last year, when the manufacturing of this product was announced, Rainbird rushed to make a similar product before patents were final. They did exactly that..they rushed..Rainbird is still "evolving" into irrigation. They were a previous high volume hose end company before they went into underground, and they still need a few more years. The Rainbird project on spinning nozzles will remain discontinued for now according to Rainbird.
